INTRODUCTION
The Preso COIN® flow meter accommodates most flows, even the most abrasive. Accuracy and reliability are achieved by its
rugged construction, practical design and simple principle of operation. It stands alone in its ability to maintain the necessary
square root relationship between flow rate and differential pressure for almost any type of flow. Even viscosities up to 3,000
centipoise do not affect the accuracy of the meter. The flow coefficient stays highly predictable down to the remarkably low
Reynolds number of 300. This makes the meter ideal for traditionally difficult-to-meter applications such as fuel oil, waste
water, coal tar, iron ores, black liquor and others.
Scope of Manual
This manual is includes installation instructions for the Preso COIN flow meter to help you get the meter up and
running quickly.
Safety Information
The installation of the COIN flow meter must comply with all applicable federal, state, and local rules, regulations, and codes.
Failure to read and follow these instructions can lead to misapplication or misuse of the COIN flow meter, resulting in personal
injury and damage to equipment.
Unpacking and Inspection
Upon opening the shipping container, visually inspect the product and applicable accessories for any physical damage such
as scratches, loose or broken parts, or any other sign of damage that may have occurred during shipment.
OTE:N If damage is found, request an inspection by the carrier’s agent within 48 hours of delivery and file a claim with the
carrier. A claim for equipment damage in transit is the sole responsibility of the purchaser.

STRAIGHT PIPE RUN REQUIREMENTS
Proper operation and performance is dependent on the required lengths of unrestricted upstream and downstream piping.
The minimum length of the upstream side of the COIN Flow Element depends on the type of fitting at the start of the straight
run, and the pipe configuration. See Figure 1. The minimum lengths will cause a slight coefficient shift.
Figure 1: Piping requirements
1. For upstream and downstream lengths equal to one half the values shown above, add 1 percent to the accuracy value.
2. Any ow conditioner shall be installed in the straight length between the primary element and the upstream distance, or
the tting closest to the element. The straight lengths between tting and conditioner shall be at least 10D and the length
between conditioner and COIN meter shall be at least 15D.
3. For other ttings or congurations, contact the factory.

SELECTING A MOUNTING LOCATION
Install COIN elements horizontally, rotated 90° along the pipe center line, see Figure 2. This method of mounting allows for free
passage of solids and eliminates air entrapment at the transmitter connection. Other positions are acceptable provided there
is proper venting of the transmitter and differences in lead line elevations are considered. Vertical installations as shown in
Figure 3 may introduce a slight hydrostatic head effect, which must be considered when zeroing the transmitter. Connections
between the COIN meter and the transmitter should be 3/8 in. (9.53 mm) tubing minimum. Use a three-valve manifold for
zeroing the transmitter.

Each flow element has an arrow indicating the required direction of flow. Failure to properly orient the COIN element may
cause improper results when using data supplied for an element that has been calibrated.
NOTES:
1. Φ =1 in./ft (80 mm/m) for water;
2...4 in./ft (60...320 mm/m for more viscous uids.
2. Minimize all lead line lengths.

NEVER EXCEED THE MAXIMUM PRESSURE OR TEMPERATURE RECOMMENDED FOR THE MEASURED PROCESS.
EXCEEDING PROPER PRESSURE OR TEMPERATURE RATINGS CAN LEAD TO PERSONAL INJURY OR EQUIPMENT DAMAGE.
THE PROCESS PIPING FLANGES SHOULD BE IDENTICAL TO THOSE ON THE COIN METER. THE PROCESS TEMPERATURE
AND PRESSURE SHOULD NEVER EXCEED THAT FOR WHICH THE ELEMENT WAS DESIGNED.
